Many experiments require a hood clue to the evolution of hazardous fumes. One such experiment involves the use of nitric acid in the determination of combining ratios of certain metals, e.g., tin and oxygen. Where large classes are the rule, as in general chemistry, and the number of fume hoods is limited, the progress of the class is slowed considerably if individual set-ups are used.
